VIM无法补全错误记录

按照教程进行安装

1. 安装 vundle

# vundle是vim的包管理器，十分好用

2. 然后安装各种插件

有些插件需要先去 GitHub 上克隆到本地。

打开 vim ，在命令模式下键入下面的插件安装指令，等待完成。

[email protected]: ~$ vim

:PluginInstall

3. 试验一下效果

再次打开 vim ，结果最下面有提示

the ycmd server SHUT DOWN (restart with ‘:YcmRestartServer‘). Unexpected error while ...M core library. Type ‘:YcmToggleLogs ycmd_41013_stderr_cys4wh16.log‘ to check the logs.

根据提示键入 :YcmToggleLogs ycmd_41013_stderr_cys4wh16.log

# /tmp/ycmd_41013_stderr_cys4wh16.log
Traceback (most recent call last):
  File "/home/cv/.vim/bundle/YouCompleteMe/third_party/ycmd/ycmd/utils.py", line 637, in ImportAndCheckCore
    ycm_core = ImportCore()
  File "/home/cv/.vim/bundle/YouCompleteMe/third_party/ycmd/ycmd/utils.py", line 628, in ImportCore
    import ycm_core as ycm_core
ImportError: /home/cv/.vim/bundle/YouCompleteMe/third_party/ycmd/ycm_core.so: undefined symbol: clang_getCompletionFixIt

原来是 clang_getCompletionFixIt 未定义，怎么办呢？

Valloric/YouCompleteMe主页查看了一下，找到了一些线索

根据指示运行 install.sh （因为 install.py 和 install.sh 运行效果一样，当然也可以使用 [email protected]: ~$ python install.py ）

[email protected]: ~$ ~/.vim/bundle/YouCompleteMe/install.sh

#!/bin/sh

echo "WARNING: this script is deprecated. Use the install.py script instead." 1>&2

SCRIPT_DIR=$(dirname $0 || exit $?)

command_exists() {
  command -v "$1" >/dev/null 2>&1 ;
}

PYTHON_BINARY=python
if command_exists python2; then
  PYTHON_BINARY=python2
fi

$PYTHON_BINARY "$SCRIPT_DIR/install.py" "[email protected]" || exit $?

install.sh

然后就ok了，现在补全功能可以用了。
